T his invention relates to improvements in looms and it consists of the matters hereinafter described and more particularly pointed out in the appended claims. 1

The primary object of the invention is to provide a loom which is universal in effect, in that either plain or patterned fabric may be rapidly woven and with which the fabric may be made in any width up to the full size width capable of being produced by the loom and this Without necessity of pulling such warps as are not required in the chosen Width of fabric and thereby eliminating subsequent rethreading of the pulled warps when a Wider fabric is to be produced.

Another object of the invention is to provide a loom having a novel shed forming mechanism including heddles of peculiar construction capable of being actuated to produce either plain or patterned fabric and any one or more of which heddles may be rendered inoperative to produce sheds, when a fabric less than one of full width is desired. V

A further object of the invention is to pro vide a loom wherein the pattern card mechanism controlling the operations 'of the heddles and associated neck bars may be actu-.

ated to repeat the patterns at desired intervals whereby a greater pattern effect maylbe attained with but a few pattern 7 control cards. 1.

Still a further object of the invention is to provide a loom having novel means for 1 checking the rebound of the weft upon insertion thereof when relatively stiff wefts are employed in the fabric, as well as other novel means for straightening such relatively stiff wefts after they are incorporatedin the fabric, by blasts or jets of compressed air.

The above mentioned objects of the invention as well as others, together with the many advantages thereof will more fully appear as I proceed with my specification.

The invention is herein illustrated and described as embodied in a loom for weaving a stake and strand fabric of reed or the like wherein the stakes or Wefts are relatively stiff when compared with the strands or warps, the fabric mentioned being especially adapted as the covering for the frame structure of certain vehicles and articles of furniture. However, it is to be understood that the invention is not to be limited to a loom solely for such fabric because, as is apparent the invention may also be embodied in looms for other kinds of fabric, where its characteristics make it desirable.

Fig. 33 is a side elevation of an attachment which is used when relatively long pattern chains are employed and Fig. 84 is an end view of the mechanism shown in Fig. 33.

Fig. 35 is a transverse detail sectional view on an enlarged scale as taken on the line 35-35 of Fig. 5 and shows the positions of the stake inserting and rebound preventing means at opposite sides of the loom.

The loom comprises a suitable frame including side plates 11 which carry the bearings for the main or drive shaft 2, the latter being operatively connected by means of the pinion 3 and spur gear a with the main counter shaft 5 (Fig. i). The latter is geared by means of sprocket wheels and the chain 6, to a counter shaft 7 which is associated with the heddle operating shaft 8 by means of spur gears 9 and 10.

The shaft 8 carries an eccentric 11 at each end, the associated strap 12 of which is pivotally connected to the bottom end of a vertically disposed reciproeable plunger 13, one adjacent each side plate 1 of the loom. Both plungers are rigid with a horizontally disposed, transverse cross bar 14 mounted upon the upper end portions thereof. Each plunger 13 is also rigid with a vertically guided rack bar 15 one at each side of the loom which meshes with a pinion 16 on a stud shaft 17 each carried by one of a. pair of upright extension frame members 18 mounted on the side plates 1. Each pinion 16 also meshes with a vertically guided rack bar 19 rigid with a cross bar 20 which constitutes a companion element to the bar 14:. Said bars 14 and 20 are slida-bly mounted at their ends in guides on the frame membe 's 18. Obviously said bars 1 1 and 20 are thus caused to move sil'iultaneously in opposite directions. Each bar is equipped along its upper edge with a flange 21, said flanges being opposed to each other and engaging in the recesses 22 of the neck bars 23 which are pivotally associated with the heddle plates 24.

Referring now to 5, 6 and 7, it will be noted that the neck bars 23, which conof relatively thin flat plates, are provided at their upper ends with heads 25 and, at their lower ends with arcnate projections 26, the latter engaging in correspondin recesses in the upper ends of the heddle plates 24. Said heddle plates are of substantially the same thickness as the neck bars 23 and are reciprocated by the latter as hereinafter described.

The heddle plates 2% are disposed in surface contact or substantially in surface contact with each other and are mounted along their upper and lower end portions, along one margin in guide grooves of opposed pairs of cross frame members 2'? and 28. Said cross frame members are arranged parallel with eacn other with their respective guide grooves disposed in sta gered relation to each other. Thus one heddle plate will be disposed along its rear margin in guide grooves in the rear frame members while its front margin will be disposed in contact with ribs between adjacent grooves of the opposite frame members. The next adjacent heddle plate would be engaged with its front margin in guide grooves of the last named frame members and its rear margin in contact with ribs of the first named frame members as will be readily understood by persons skilled in the art.

owing to the fact that, alternate sets of the heddle plates and neck bars are of different lengths with resp ct to intermediate sets as is apparent from Fig. 5, the pivotal associations thereof with the respective neck bars will not permit of any relative lateral movement of any neck bar with respect to its heddle plate so that there can be no release or interference with these pivots during the opration of the loom.

Each heddle plate provided bctw on its ends with a slot 29 extending from front to rear edge thereof and of a width equal to the thickness of the plate, said thickness being of substantially the (hair eter of the strands which pass through said slots. Each slot is spanned by an integral 1 midge piece 30 which is bowed and pro ects from one face of the plate. The said slots extend. angularly ofthe front and rear edges of the plates 24. and in intersecting relation to each other with respect to contiguous plates. In other words the slots 29 of alternate heddle plates 24 extend downwardly from the rear to the front edges thereof and in the intermediate
